How to correct spelling in Dictation on new iPad (3rd generation)

The Dictation feature on iPad (3rd generation) insists that Clare is spelled Claire, and I have been unable to find a way to correct this, other than manually placing the cursor, which is fiddly and rather defeats the point.

I have looked online for tips, and have not found any useful information so far. There is this Apple page iPad (3rd generation): Using Dictation, that has a very short "Dictation tips" section, but it currently only covers selection of different languages.

Is there any way to have control over the vocabulary, or spelling, of the Dictation feature?

I found the answer from iMore's How to turn on and use Siri-like Dictation on your new iPad:

If Dictation gets confused about any of the words you speak, it will underline them in blue on the screen. If the word is incorrect, tap it to get a popup menu with alternatives. Tap an alternative to switch to it. You can also simply edit voice dictation text like any other text.

Sure enough, single-tapping on Claire gives me an option to change the text to Clare, and of course it works other ambiguous words.

A particularly useful example is when you mean Buy, and the dictation types By, with a blue underline. Tapping on that gives the two alternatives Buy and Bye.
